Solution Overview

Problem

Conventional chat applications limit the ability for multiple users to collaborate on drawing pictures and understanding each other's intentions, as they do not allow real-time collaborative picture drawing or efficient searching of previously completed images.

Innovation Solution

A turn-based pictorial chatting method and application on user terminals that enable multiple users to draw and share pictures in chronological order, allowing for accurate understanding of intentions and easy retrieval of completed pictures through text-based indexing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional chat applications use predetermined static or dynamic images to display user emotions, then the chat application is simple to operate, but the degree of freedom and expressiveness are limited

Engineering Contradiction:
ImproveexpressivenessVSAvoidsystem complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent replaces the mechanical system of selecting from predetermined images with a digital drawing system using touch screens. Users can freely draw pictures to express emotions and intentions, transforming the rigid image selection process into a flexible digital creation process that enhances adaptability while maintaining operational simplicity through intuitive touch interface

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent changes the parameter of image content from fixed predetermined images to variable user-drawn images. This allows the chat application to adapt to diverse emotional expressions and communication needs while maintaining a simple interface, as the system handles the complexity of generating and managing unique images automatically

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If a user manually inputs handwriting to communicate directly written text or drawn pictures, then the user can express personal thoughts, but only one user can display their content to another user simultaneously

Engineering Contradiction:
Improvecollaborative capabilityVSAvoidcoordination complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent merges multiple users' drawing operations into a single shared canvas. Multiple users can simultaneously draw on the same picture, with their contributions combined in real-time. This eliminates the limitation of one-user-at-a-time display and enables collaborative picture creation while the system automatically manages the complexity of coordinating multiple input sources

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a server as an intermediary to manage and coordinate drawing data from multiple users. The server receives drawing information from each user terminal, processes and integrates the data, then distributes the combined picture to all participants. This intermediary handles the coordination complexity centrally, allowing users to collaborate freely without direct coordination overhead

Inventive Principle:
Principle #24Intermediary (Mediator)

3Loss of information

If pictures are drawn and sent by the chatting party without structured process tracking, then users can communicate freely, but it is not easy to accurately understand the user intention to be transmitted by the picture

Engineering Contradiction:
Improveintention understandingVSAvoiddata structure complexity
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent segments the picture communication process into distinct phases: drawing phase, completion phase, and transmission phase. By tracking the process state and dividing the communication flow into manageable segments, the system can accurately capture user intentions at each stage while maintaining a clear data structure that manages the complexity of process tracking

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements feedback mechanisms where the system tracks and stores the drawing process information, then provides this information back to users for review. This feedback loop ensures that the original user intention is preserved and communicated accurately, while the automated tracking system handles the data structure complexity without burdening users

Inventive Principle:
Principle #23Feedback

4Ease of operation

If previously completed pictures are stored without indexing, then all chat history is preserved, but it is difficult to search for specific pictures received in previous chats

Engineering Contradiction:
Improvesearch efficiencyVSAvoidindexing system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies preliminary action by automatically generating and storing index information (such as text descriptions, keywords, or metadata) at the time a picture is created or received. This pre-indexing enables efficient future search operations without requiring complex retrieval systems, as the search infrastructure is prepared in advance with the necessary indexing data already in place

Inventive Principle:
Principle #10Preliminary action

AI summary

The present invention relates to a turn-based pictorial chat application installed in a user terminal and a method for a pictorial chatting. The method comprises: storing a process of completing a picture in a chronological order from a start of drawing the picture when a first user draws the picture through a picture input window displayed on a display part of a user terminal, wherein a plurality of stage data capable of distinguishing positions are inserted according to a degree of completion of the picture; transmitting the stored picture to a user terminal of a second user as a chat participant; displaying the transmitted picture on a display of the user terminal of the second user; and displaying the picture drawn on the user terminal in chronological order according to the selection of the second user or displaying the picture at the position where the stage data is inserted according to the selection of the second user.
